Running at the low end cuts switching losses and lets you use a lossier core material; pushing toward 1 MHz shrinks the magnetics but demands tighter layout and faster gate drive. The part includes a clock sync input so you can lock multiple converters to the same frequency — useful when you have a sensitive analog rail and want to dodge beat-frequency ripple. ## Control features for sequencing and soft start Enable, frequency control, ramp, and soft start are all on the pinout. The soft start pin lets you set the inrush ramp with a single capacitor, which matters when the load is a big FPGA core or a bank of electrolytics. The ramp pin gives slope compensation for continuous-conduction-mode operation above 50% duty cycle — a detail that saves you a re-spin if you are pushing the input-output differential. ## Package and footprint Housed in a 16-lead HTSSOP with an exposed pad, the part needs a thermal via array under the pad to pull heat into the board plane. The PowerPAD is the main thermal path — without it the junction-to-board thermal resistance climbs fast. The supplier device package is 16-HTSSOP; the case code is 16-PowerTSSOP, 4.40 mm width. Tube shipment is the standard for prototype and low-volume builds; reel options exist through the supply chain. ## Lifecycle and compliance The LM25088MH-1/NOPB carries an active product status and is ROHS3 compliant. For new designs this part is a safe selection; no successor has been announced.","metaTitle":"LM25088MH-1/NOPB Buck Controller, 50kHz-1MHz, 16-HTSSOP","metaDescription":"LM25088MH-1/NOPB is an active step-down buck controller from TI.
